Abstract
We have investigated the molecular dynamics in the nematic liquid crystal 5CB
using the ALC µSR technique. Our
measurements are consistent with a change in the amplitude of director
fluctuations at the nematic-isotropic transition and we develop a model to
describe this.
Keywords: Nematic; Director fluctuations
